Group 1 - The core viewpoint of the article highlights the commencement of the summer harvest and planting season in China, marked by the release of the first national meteorological service report for summer harvest and planting in 2025 by the Central Meteorological Station on May 20 [1] - The summer harvest primarily involves the collection of winter wheat and rapeseed, while summer planting includes the sowing of summer corn, summer soybeans, and transplanting of rice [3] - The meteorological report predicts favorable weather conditions for the majority of summer grain-producing areas, with a low risk of continuous rain, which is beneficial for the maturation and harvesting of winter wheat and rapeseed [3][5] Group 2 - The report indicates that from June to mid-June, temperatures will be close to or slightly above the normal levels, with precipitation in North China and the Huang-Huai region being near normal, which is conducive to the smooth progress of wheat harvesting [5] - However, localized severe weather such as heavy rainfall and strong winds may impact the harvesting process [5] - The China Meteorological Administration is utilizing satellite remote sensing and radar monitoring to provide technological support for summer agricultural production, including monitoring crop growth and soil moisture [5][7] Group 3 - The article discusses the phenomenon of "dry hot wind," which poses a risk to winter wheat in northern regions, particularly during the critical growth period of flowering to grain filling [9] - "Dry hot wind" is characterized by high temperatures and low humidity, leading to increased transpiration and potential yield loss in wheat crops [9] - Historical data indicates a decreasing trend in the intensity of "dry hot wind," but recent climate warming has led to higher temperatures during the grain filling period, increasing the risk of this weather phenomenon [9]
